Study shows unrelated friends share same genes

Geneticists from the U.C. San Diego and Yale University have partnered and found that unrelated friends share many of the same genes. These genetic similarities are akin to those of actual blood relatives. Equal to something like fourth cousins. Meaning, friends might share more than just the love of the same kind of music.

They could have more DNA in common with each other than perfect strangers.

Scientists say these findings could stem from when early humans may have formed groups that were genetically suited to the same environments. Those that were built the same had a better chance at surviving longer. These bonds still might hold true today.
